Transferable Skills - how can I stop being pigeonholed in one role?

I've been Celeb booking for over 20 years and I get pigeonholed as ONLY being able to do that role. I have experience in topical comedy research and have contributed valuable creative ideas for VTs and sketches. Away from TV I have done creative consultancy work, pitching ideas for brands, which I've really enjoyed. I also run a lot of events and campaign work locally. So my question is this: how do I use my full range of skills in TV?
